Answer:

Yes you are correct. It is x^4/21 or C.

Step-by-step explanation:

x^-2/3 • x^6/7

x^ -2/3 + 6/7

x^ 7(-2) + 3•6 / 3•7

x^ -7 •2 + 18 / 3•7

x^ -14 + 18 / 3•7

x^ 4 / 3•7

Michael has a fish tank that has a length of 7 inches,a width of 6 inches and a height of 8 inches. What is the total surface ar

White raven [17]

Answer:

292 inches^2

Step-by-step explanation:

So to start off this is a picture of the fish tank.

Next we will find the area of the bottom and top rectangles.

The side lenghts for those two is 7 and 8.

So the area of one is 56 and the area of 2 is 112 inches^2.

Now we will find the area of the left and right rectangles.

The side lenghts are 6 and 8.

So the area of 2 is 96 inches^2.

Now for the front and back rectangles.

The side lenghts for those two are 6 and 7.

So the area of both is 84 inches^2.

So after adding all the areas up the surface area is 292 inches^2.

We need help finding the means of the sides of this figure.<br> (Photo attached)<br><br> Thank you

Answer:

3) 5

4) 8.2

5) 6.8

6)FG = 6.4

7) EF = 3.6

8)DF = 4.8

Step-by-step explanation:

From the attached triangle, using trigonometric ratio we can find ∠G as; tan^(-1) (6/8)

Thus, ∠G = 36.87°

Still using trigonometric ratios;

FG/8 = cos 36.87°

FG = 8 cos 36.87°

FG = 6.4

3) EF + FG = EG

Since EG is 10, mean of EF and FG = 10/2 = 5

4) mean of EG and FG = (10 + 6.4)/2 = 8.2

5) EF + FG = EG

Thus; EF = EG - FG

EF = 10 - 6.4

EF = 3.6

Mean of EG and EF = (10 + 3.6)/2 = 6.8

6) FG = 6.4

7) EF = 3.6

8) Using trigonometric ratio;

DF/8 = sin 36.87

DF = 8 × 0.6

DF = 4.8
